Это прекрасное дополнение, которым всегда пользуюсь. Но есть одна существенная проблема. После закрытия браузера слетает группировка вкладок, что очень разочаровывает. Надеюсь, проблему исправят.

nice and simple

Tried it as I saw it suggested. Tree Style Tab user here, but it's not possible to middle click to close a group of tabs. Maybe if this is implemented I might try again. It feels like this extension maybe tries to do too much?

I only used for about an hour, so maybe that's why?

Totally unusable. It just eats my tabs, and assumes WAY too much about my workflow. A way to turn off the panel stuff would be appreciated—that's what hierarchical tabs are for!

Groups are, just, I mean, *what*? I don't get it. You have to select multiple tabs just to create a folder? This is unprecedented in the history of computers. Even file compression tools let you create empty archives.

Excellent! It should be FF by default :-) Gives more space verticaly on your computer screen. One can see tab names regardless of number of tabs which makes reviewing and switching between tabs quicker and easier.

Just what i was looking for!

Thanks, it is lovely (and most practical of course) !! ;)

best

Поставил после того как услышал от @bobuk в подкасте Radio-T, классное расширение, именно то что мне нужно, особенно радует иерархия

Superb. I'm hugely impressed by amount of features, details and configuration options in this extension. Used Tree Style Tab for months and now Sidebery is my extension of choice.

There is only one (but quite big) issue with usage of this extension, but it's not really fault of the author. Lack of customizable keyboard shortcuts, especially being able to bind switching to next/previous tab to something like CtrL+Q/Ctrl+E. That's an absolute shame for Firefox that it doesn't allow that.
